The present invention is primarily (116* signed "for usein street-cars and particularly for cars' making a certain limited trip between. two distant pointsand returning, on.

a the same line. from one point to the; other.

Existing devicesof thls kind have; mostly been madestationary at both ends of the car, and SGTG tall attempts have"beenan'ladeito make a removable upper portion of the turnstilewvhich may be t ansiierlred from one end to the other by attaching it to -fixedly placed stands at both ends of thescar. @These stands have mostly contained all mechanism,

as for instance, a release operated by the V conductor, acounter, one-way clutch: andr other devieesnecessanv for t'he-opera-t'ionof. the tur-nstile. The onlyporinon moved from;

EX-tending sidewaiidly from, and 7 adapted: to oscillate, is a plnr'ality. of spring-controlled arms 9' so arranged; as to permit the upper portion 1O of the arms to be pressed forward when a person; attempts to pass the turnstile. Forming a portion of the armsis a pawl 11 intended to register with alocking' device LQand adapted to: render. the latter inopen ative: when the upper-arm, portion-10: is pressed 7 cforwardl T1113: locking device comprisesa lever; i ted at'lQ, and provided vithian in'clinedi upper facev 12", which face, 1s adaptedto. be engaged by .p'awls 11 of "the. arms; Theinner portion of the lever is provided. with: a depression 12".Wl1lCl1'tBP- minatesinlani abutment L12. .This abutment lsadaptcdato placeitseht in the path of four lugs 1125, forming integral parts ofrotary member 170i the head. Lever 12 is held in its normal upward position by a spring, not shown in the drawings. Its upward move ment however is limited by the lower peripheral ledges of member 17 disposed between the four lugs 112. The moment the in clined face of lever 12 is engaged by pawls 11, the abutment 112 of the lever is depressed below the face of the lugs 112. The moment pressure against the arm is relieved, lever 12 assumes its normal position and is ready to engage the next following lug. By means of this locking device, thearm following the one which has been operated, is stopped from continuing the motion of the operated arm. A coil-spring 1;) provided in connection with the arms (see Figure 2) causes the upper-arm portions to always assume a position inclined toward the operator. The head further consists of a relatively stationary member 141 through the center of which passes a shaft which is keyed to the member 14. by any suitable arrangement indicatedat 15 and is thus prevented from rotating. lVithin the hollow part of member 14 there is provided a rollerbearing indicated at 16. upon which rests the movable member 17 of the head. Arranged about bearing 16, and depending from plate 18 of movable member 17, are a plurality of fixed detent elements, in'this case rollers 19. Arranged also within the hollow part of the stationary member 1 1, there is a movable element of the detent, in this case a bar 20 which is held in pressing relation against rollers 19 by means of a tension spring 21. This arrangement is provided for the purpose of assuring the positioning of the movable member of the head.

Keyed to shaft 15 above plate 18 of the vmovable head member 17, and arranged within the hollow space 17 of movable head member 17, there is arranged a frictionclutch disk 22 provided with a. plurality of recesses-indicated at 22, within which are lodged vertically disposed rollers 23,

Against these rollers bear springs 2 1 so as to cause the rollers to always be in frictional engagement with the recessed portion 22 of the disk 22 and the annular surface 17 of member-17. It is obvious that when member 17 is rotated in clockwise direction,

' rollers 23 will be pressed against springs 24:

and therefore will permit the rotation of member 17. ,If, however, the latter is moved in opposite or anticlockwise direction, rollers 23 will be wedged between the recessed portion 22 of friction-disk 22 and the inner annular periphery of member 17, thus preventing the latter from turning.

Rotary member 17 is hollowed out at its upper portion as indicated at 25, and at its center forms a hub 26 providedwith a bore 27 registering with vertical shaft 15 about which the member 17 rotates; At the upper portion of hub 26 there is provided a gear 28 meshing with another gear 29 attached to the stationary base 30 of the countermechanism.

Operation.

of my device, I shall assume it is used in a street, car where at both ends of the car are provided l1glCll)"2lfi1X6Cl standards near the respective entrances into which the head ofmy device may be readily inserted and where it may be firmly held against dislocation.

lVhen the entering person passes into the car, the upper portion 10 of an arm 9 is pressed forward, thereby depressing lever 12 of the arm-locking mechanism. The latter is thus released and permits the rotation of the movable portion of the head. With each quarter revolution, both the totalizer and the trip-counter are operated. When the quarter revolution is completed, the detent sets the head with its arms in the proper position to receive the following person entering the car.

The cletentnieclianisin is so arranged that when one of the rollers 19 thereof pressingly engages detent bar 20 and passes over substantially the latters center, the spring 21, expanded by that roller 19 pressing against bar 20, causes that bar 20 to firmly press against roller 19 and causes it to assume its normal position as indicated in Figure 5.

At the .same time looking lug 11 has engaged lever 12 of the locking arrangement, thus preventing the further turning of the rotary part of the head until the upper arm portion 10 of next'arm is pressed against, and releases the locking lever 12.

From the foregoing, it will be evident that my device is very simple in operation and has the advantage of concentrating the entire mechanisms used in turnstiles in the removable'head. This advantage becomes of great importance not only for the use of one head in a car with double standards, butalso in the event that a head, for instance, would get out of order or may otherwise become inoperative. In such case, another head carried in stock may readily take the place of the defective one without entailing a loss of time due to the removal of the entire standard as has been necessary heretofore.

Another advantage of my device is its compactness and the ability of the users to store away the complete heads with the entire mechanism during the winter months when a lesser number of cars is operated. In companies using special summer and winter cars. the advantage of applying my device is very obvious for the reason that they merely have to transfer the heads to the respective standards in the cars used at the time, thus elim inating the double purchase of expensive turnstile mechanisms permanently attached to cars as was heretofore the case.

While I have shown in the drawings a specific construction of my device, be it understood that various changes and improvements may be made to allow the application of my device, under various conditions, with out departing from the broad scope'of my invention of a removable turnstile head comprising turnstile mechanisms lndependent of II the standard in which the head operates.

standard, an operating head, transferab'ly mounted upon said standard and comprising stationary and revoluble members, a plurality of spring-controlled operating arms associated with the latter member, arm-locking means associated with the stationary member, and means forming part of the arms for, releasing said locking means.
